No. 

vmware (workstation) includes a linux kernel module  - this 
runs inside the linux kernel in "ring 0" and uses this fact
to provide its virtualization functionality. With Xen, only 
Xen itself runs in ring 0 - even dom0 runs in ring 1, and so 
cannot provide this functionality. 


cheers,

S.
